慢性酒精中毒性周围神经病的神经电生理检查分析

目的探讨神经传导速度（NCV）和H反射对慢性酒精中毒性周围神经病（CAPN）的诊断价值。方法选择慢性酒精中毒性周围神经病患者和健康对照者各60例，用肌电图诱发电位仪检测正中、尺、腓、胫神经NCV，并在胭窝引出H反射。结果患者组的NCV及H反射与对照组比较异常率明显增高（P〈0．01）；下肢运动神经传导速度（MCV）异常率高于上肢；感觉神经传导速度（SCV）异常率高于MCV。结论NCV及H反射检查对酒精中毒性周围神经病的诊断有参考价值。

study on peripheral neuropathy of chronic alcoholism

Objective To explore the diagnostic value of nerve conduction velocity（NCV） and H - reflex in patients with peripheral neuropathy of chronic alcoholism. Methods Sixty patients with peripheral neuropathy of chronic alcoholism served as experimental group and 60 healthy subjects as the control group. NCV of the madian, ulnar, peronea I and tibial nerves were measured and H - reflex was elicited by electromyography. Results A significant difference in NCV and H - reflex was noted between experimental group and control group. H - reflex and SCV were more sensitive than MCV. The abnormal rate of lower limb was higher than that of upper limb, and that of SCV was higher than that of MCV. Conclusion The NCV examination and H - reflex is one of diagnostic value to chronic alcoholic peripheral neuropathy on the early stage.
